ADOLPH AN DERSON, OF CHICAGO, ILLINOIS, ASSIGN OR TO AURORA AUTOMATIC MACHINERY 00., OF CHICAGO, ILLINOIS, A CORPORATION OF DELAWARE.

Specification of Letters Patent.

Patented July 16, 1918.

Application filed July 12, 1917. Serial No. 180,121.

To all whom it may concern.

Be it'known that I, AooLPH ANDERSON, a citizen of-the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Governor Mechanism for Sprin -Motors, of which the following is a speci cation.

The present invention relates to a governor mechanism for spring motors more particularly designed and adapted for use in connectionwith talking-machines.

The object of the invention is to provide a simple means for actuating the governor to control the speed of the motor; and to so construct said actuating means'as to prevent the overthrow thereof.

The invention further consists in the features of construction and combination of parts hereinafter described and claimed.

In the drawings: Figure 1 is a front elevation of the motor of the present invention, showing a portion of the turntable and casing of a talking,

machine in section;

Fig. 2, a section along line 2-2 of Fig. 1, looking in the direction of the arrows.

Referring now to the drawings, particularly to Fig. 1, the motor is shown as suitably positioned with respect to a casing 7 of a talking-machine, which casing may be of any suitable size and style. Mounted to revolve above said casing is a table 8 of suitable character, upon which is placed the usual fiat disk-like talking-machine record.

The motor, which is the part to which the present invention relates, is carried by aholder comprising what may be termed an upper part 9 and a lower part 10, these terms being used in conformity with the way in which the partsare shown in the drawings. The upper portion 9 is in the form of an integral metal member and consists of a plate 11, depending from which are lugs 12, 13, 14 and 15, the lugs 12 and 13 being longer than the lugs 14 and 15. The lower part 10 comprises a single plate 16, which is secured by suitable fastening members 17 to the lugs 12 and 13. Thus, the

complete holder for the motor consists: of only two parts, making it very strong and rigid of construction and enabling an easy and quick assemblance and disassemblance.

Mounted between the plates 10 and 11 is a double spring barrel 18 consisting of an upper drum 19 and a lower drum 20. Extending through said drums is a rod 21 journaled in the upper and lower plates 11 and 16 respectively. This rod acts as a bearing on which the motor revolves. Each of the drums contain a spring, which springs act to revolve the drums and drive a suitable and desired train of gears.

Secured adjacent the bottom of the lower drum 20 is a gear 26, which, as shown, is of bevel formation, and with which meshes a bevel gear 27 on a wind-up shaft 28. This wind-up shaft is journaled in the lugs 13 and 15. The end 29 of said shaft is arranged to receive a suitable form of winding crank; and secured to the lug 15 and extending around said shaft is a clutch in the form of-a spiral spring coil 30.

Connected to the upper drum 19 is a gear 31, which meshes with a pinion 32 on a shaft 33 journaled in the plates lOand 11.

Connected to this shaft 33 is a gear 34 meshing with a pinion 35 on a shaft 36, which also has its bearings in the plates 10 andll, and one end 37 of which extends above the plate 11 and iskeyed or otherwise secured to the turntable 8 of the talking-machine.

Also mounted upon the shaft 36 is a spiral gear 38, with which meshes a spiralthread 39 on a governor shaft 40, upon which is slidably mounted, in the usual manner, a spring arm ball governor 41. Associated with the governor is a disk 42, against which rests a plug 43 of felt or other suitable composition. This plug is connected to an arm 44, which in turn is joined to an arm 45 pivoted in lugs 46 extending from the plate 11 and is held normally outward by a .suit-.

able spring (not shown). a

The arm 45 extends outward beyond the lug 12, and a speed controlling member 46 is provided for actuating said arm. Said controlling member consists of a revoluble portion 47, depending from which is a stem 48, which stem carries a bent portion 49 adapted to engage the rod 45. As the member 47 is turned, the stem 48 turns, which turns the bent portion 49, and this latter acts in the manner of a cam to depress or lower the arm 45,- which movement of the arm, 45 swings the arm 44 in and out, moving the felt plug 43 in and out, and thus influencing the position of the disk 42, with the resultant release or contraction of the governor and the movement or stoppage of the motor.

As will be seen from Fig. 1, the bent portion comprises a bend 49* at its .inner end and a bend 49" at it outer end. The rod 45 so engages the portion 49 that when said portion is turned the maximum distance desired in either direction, the arm will engage with either the bend 49 or 49, depending on the direction of movement of the member 49; and when such engagement is made, will stop further movement of the member 49 and thus prevent any overthrow thereof.

The principle upon which these governors work is well known and it is not thought necessary to explain the same at the present time. The novel feature of this particular portion of the mechanism is deemed to reside in the bent portion -19, which forms a very simple and effective means for operating the speed control.

I claim:

In a governor mechanism for spring motors for talking machines, the combination of a driven shaft, a governor shaft geared to the driven shaft, governor mechanism on said governor shaft, means for controlling the position of the governor mechanism on its shaft to determine the speed of the driven shaft, said controlling means comprising an L-shaped lever pivoted intermediate its ends, one free end of the lever engaging the governor mechanism, a pivoted post, a fingerpiece on the upper end of the post, a scalesurface in juxtaposition to said post, a member secured to the post and bent to extend outward therefrom, then upwardly to form a bend at its inner end, then downward in an eccentric manner from said inner bend and continuing downwardly to form an outer bend, the other free end of the L-shaped lever being engaged by the under side of said bent member and moved by actuation of said member to swing the L-shaped lever back and forth about its pivot and cause a movement of said governor mechanism, and the inner and outer bends in said member engaging the lever to limit the movements of said post, Substantially as described.
